Digium VoIP Gateway The G100 and G200 are the first in a family of cost-effective VoIP gateways that simplify the process of deploying converged media networks.

Built on a powerful combination of the Asterisk open source communications engine and a state of the art embedded platform, the gateways provide the best value for Asterisk connectivity.

Digium’s gateways are built to support TDM-to-SIP, SIP-to-TDM and SIP-to-SIP (transcoding) applications. In a TDM-to-SIP deployment the gateway significantly reduces operating costs by connecting a legacy business phone system with dynamic SIP trunking services. SIP-to-TDM deployments use the gateway to connect a modern SIP communications system with T1/E1/PRI service from legacy carriers.

The gateway software is based on the Asterisk communications engine and is managed through Digium’s intuitive point-and-click GUI interface, which allows for easy navigation and effortless setup. The gateways feature a power-saving embedded design with a highly efficient digital signal processor (DSP) handling all mediarelated operations.

The G100 includes a single software-selectable T1/E1/PRI interface and supports up to 30 concurrent calls. The G200 doubles the capacity with two T1/E1/PRI interfaces and up to 60 concurrent calls. Both models have integrated echo cancellation, a small footprint (1U, half-width, half-depth) and no failure-prone moving parts.
